removing 2 rear mufflers

[shaunv8]

Hi all,

I have an 03 e53 4.4l. Im in Australia BTW.

I have been to a few exhaust guys as I simply would like a little more of a V8 note from the X. They have all recommended removing the 2 rear mufflers and replacing with straight through pipe, still with quad tips. So basically leaving the 1m long centre muffler in place.

Has anyone done this and can comment on the sound? Or even a soundfile would be awesome.

Cheers Shaun

It's illegal mate. Spend a bit more, get 2 small sport mufflers + remove the resonator and enjoy Euro V8 music to your ear!!!
Dandy Exhast (sth east melba) quoted me all up at around $350. Unless you want to use Euro Spec tuning house then be ready to pay around 2k but will definitely sound better.

Is it illegal because of the noise issue? In the US, a lot of M5's took off their exhaust cans and it sounds great. I love the way mine sounds on the M5. It's cheap and sounds better than my aftermarket cans I put on previously. You can always just remove the cans and try it out for a few weeks. If you don't like you can put your original cans back on or put some sport cans on.

Cant' go wrong with the M5 whether it has exhast or not, standard or after market ..... the thing just sounds so porn. Lucky you.

Did you have to do your Smog test? My bro in LA has a 2010 R35 GTR with a titanium catback exhaust (half or quater back whatever you guys call it), he's been ringing me up for advice on Mods, i told him to start off with a full exhaust but he's a bit worry about the SMOG test so i told him its a PART of the game .

No smog test yet but I didn't have a problem when I had the magnaflows and there are no reported problems on the forums. Your friend shouldn't have a problem unless he removed the cats. He just has to make sure that the car is fully warmed up before testing. I would even suggest holding the revs 3-4k for a minute or 2 just before getting the car tested to make sure everything is hot. This is what I did for my modded turbo Audi with high flow cats and it passed. Also since his is AWD, he only needs to rev in neutral so the engine is even less stressed.

In terms of mods he should just wait till he's out of warranty and then get a tune for the car so he can unleash Godzilla!!

I told him to get ALPHA12 kit .... = 1200HP .

My friend did this to his E39 and it sounds sick. SO NICE for removing just the exhaust cans (and quite a weight reduction as well)
